There is a need to develop effective antibacterial therapies for mitigating bacterial pathogens in food systems. We used a 3D checkerboard assay to ascertain a safe synergistic combination of food-grade components: vitamin C, copper, and the essential oil linalool. Individually, these constituents have to be added in large amounts to exert their antibacterial effect, which leads to unwanted organoleptic properties. The triple...

Since siderophores have been widely exploited for agricultural, environmental, and medical applications, the identification and characterization of new siderophores from different habitats and organisms will have great beneficial applications. Here, we identified a novel siderophore-producing gene cluster in C. necator JMP134. This gene cluster produces a previously...

Polη was shown to be critical for cell growth in the yeast Saccharomyces cerevisiae, and deletion of its corresponding gene RAD30 caused a severe growth defect under exposure to oxidative stress with 2 mM H2O2. Furthermore, we found that Lsm12 physically interacts with Polη and promotes Polη deubiquitination and recruitment. Overall,...

“Candidatus Methanoperedens nitroreducens” is an anaerobic archaeon which couples the reduction of nitrate to the oxidation of methane. This microorganism is present in a wide range of aquatic environments and man-made ecosystems, such as paddy fields and wastewater treatment systems. In such environments, these archaea may experience regular oxygen exposure. However, “Ca. Methanoperedens nitroreducens” is able to...

Iron is essential to almost all organisms, but in the presence of oxygen, iron is both poorly available and potentially toxic. Streptomyces species are predominantly present in soil where the environment is complex and fluctuating. So far, the mechanism of iron homeostasis in Streptomyces spp....
